Mokuba no Kiseki seeks to bring gamers to the very origin of the Gundam. The story is based on the One Year War, the player is the leader of the 13th Independent Regiment Bright Noa. Send Mobile Suits out to the field to take down your enemies, and call them back to protect the White Base when situations get dire.

The strategy simulation is simplified and the system is more intelligent, so that even gamers that are unfamiliar with counting squares and making formations can shoot down their enemies effectively. Once the gamer gives the order, the mechas will approach their enemies to make war. And when attacked, their units will fire back automatically.

Veteran strategists can create complicated tactics and give detailed instructions to their units to increase the effectiveness.
